# Event-Based Analytics

**Definition:** Event-based analytics models user activity as a stream of discrete, timestamped events - each with a user identity and descriptive properties - rather than as pageviews grouped into sessions. Any behavior becomes analyzable: a funnel is a sequence query over events, retention is a recurrence query, a cohort is a filter on event history.

## Why did the event model replace the pageview model?

Because products stopped being pages. Single-page apps, mobile apps, and multi-device use broke the assumption that a 'pageview' means anything, and business questions became behavioral: not 'how many visits' but 'do users who import data in week one retain better.' The event model answers those directly; the pageview model approximates them badly. GA4's own move to events - and Adobe's CJA - are the incumbents' concession on this point.

## What are the costs of the event model?

Design responsibility. Pageviews collect themselves; events must be chosen, named, typed, and owned - the tracking-plan discipline. And event-based pricing turns taxonomy sloppiness into invoice line-items. The model's power and its maintenance burden are the same fact viewed from two sides.

## FAQ

### Is GA4 event-based analytics?

Structurally yes - GA4 records events. But its analysis layer, retention limits, and design center remain marketing-shaped, which is why product teams still adopt dedicated event-analytics platforms alongside or instead of it. The model is necessary; it isn't sufficient.

In practice: Designing the event stream is the first week of our implementation sprint. (https://ampl.webclat.com/services/amplitude-implementation)
